Title: Multiple spit carrier for barbecued food - has ends of several spits clamped between pair of fire resistant strips
IPC: A47J37/06
Filed: 1973-04-04

Title: Coal breaking and crushing appts. - has lifter shelves positioned at set angle of incline on drum
IPC: B02C17/00
Filed: 1975-11-03
Abstract: The appts. for reducing coal and other materials, includes a hollow rotatable drum having an opening to receive feed material and wall means including screening openings to discharge material of desired size. Lifter shelves are positioned on the inner surface of the wall means for lifting and dropping material within the drum as the drum is rotated. Rotor includes a rotor shaft and shaft-mounted material impacting means positioned within at least a portion of the length of the drum for impacting material dropped from the shelves. The drum drive means is connected to the drum driving it at a speed in the range of about 70% to about 95% of critical speed. The lifter shelves are positioned on the drum at predetermined angle of inclination, ranging from 0 deg. up to 70" in a direction opposite to the direction of drum rotation. This angle causes the material to drop from the selves into contact with the impacting means at or near the crest of the orbit of the impacting means when the drum is rotated at the speed which directs the material from above one side of the rotor shaft to the other side of the rotor shaft in the direction of the down running side of the rotor shaft.

Title: Repetitive alarm trigger circuit - uses capacitor charging and discharging through different resistors to control repetitive timing
IPC: G08B13/00
Filed: 1976-05-12
Abstract: The repetitive alarm trigger circuit is designed for the protection against breakin of premises. The alarm circuit is triggered by the closure of a contact which puts into operation a first timing interval between two alarms. At the same time a second alarm duration timing interval is actuated. The first time interval is obtained from the change time of a first capacitor change through a first resistance. The second time interval is obtained from the discharge time of this first capacitor through a second resistance. The first resistance forms parts of a change circuit consisting of a first transistor which closes the circuit when the transistor is conducting. The second resistor forms part of a circuit which is closed during the alarm period.

Title: Thick low density felt formed from impregnated lap - which is broken into fibres pneumatically and deposited on perforated surface
Inventor: GILLARD PAUL HENRI
IPC: D04H1/00
Filed: 1976-07-08
Abstract: A thick low density felt is produced from a carded lap of e.g. natural or synthetic fibres at which an adhesive is sprayed at a spraying station. The lap is then fed into a pneumatic felting device which breaks up the fibres into a homogeneous mass using air currents. Finally the fibres are deposited as a felt on a perforated support surface having the form of a perforated roll or a perforated plate. Suction is applied to the underside of the support surface. The felt is thick, has low density and is highly uniform, thereby eliminating flaws and reducing breakages.
Patent FR-2319788-A1 (FR)
IPC: G01F11/08
Filed: 1976-07-27
Abstract: In the pump cylinder (13), used as feed chamber (15), the fluid product is taken in, via a non-return valve (22), by the upwards movement of the piston (14). On the downward movement of the piston (14), the product passes, under pressure, via through-passages (31) into a discharge chamber (32). An annular plunger (33) loaded by a strong spring (36) is raised and an increased receiver pressure is set up in the chambers (15 and 32). When the piston stroke is completed, a tap valve (42), provided in the piston (14), makes contact with a stop (46) and connects the feed chamber (15) to the discharge outlet (16), out of which, as a result of the prevailing increased receiver pressure, the product is ejected in a spray-like manner. In this manner, it is possible to spray a fluid without using propellant, the spraying pressure and the respectively sprayed volume of fluid being independent of the pressure which acts on the piston (14) on its downwards movement.

Title: IC engine combustion chamber - has wedge shaped cutouts in cylinder head and piston crown to produce turbulent inlet flow
IPC: F02B31/00
Filed: 1977-03-24
Abstract: The cylinder head is provided with a wedge shaped combustion chamber (4) communicating with the intake port (5) via the inlet valve (6). The spark plug (7) extends into the blunt end of the combustion chamber. The piston crown has a recess (8) corresponding in shape to the cylinder head combustion chamber with the respective blunt ends (4a, 8a) opposite to each other and the opposite surfaces parallel. The two parallel surfaces form a compression zone at piston top dead centre. The inlet valve is set at an angle to the cylinder axis, which causes the incoming gases to flow to one side of the combustion chamber. A turbulent flow follows to form a gas ring which benefits ignition when an exhaust feed back system is employed.
